Hybrid molecules based on C₆₀ fullerene and strained polycyclic hydrocarbons have been synthesized for the first time using the Bingel–Hirsch reaction. Thin films based on the synthesized hybrid compounds have been obtained and their surface morphology has been studied. Organic field-effect transistors have been fabricated based on thin films of the С₆₀ fullerene adducts bearing fragments of strained polycyclic hydrocarbons. Current-voltage characteristics of the transistors have been measured and the mobility of the charge carriers has been calculated.

: For the first time, a sonochemical method has been developed for the structural rearrangement of [5,6]-open mono- and poly adducts of fullerene C60 containing spirocyclic fragments of camphor analogs into [6,6]-closed isomers. The isomerization reaction occurs with quantitative yield under mild conditions: 1 hour at room temperature. A probable mechanism of sonochemical isomerization has been proposed. Mono- and poly adducts of C60 fullerene containing spirocyclic fragments of camphor analogues were obtained in the reaction of metal complex catalysis by the Pd(acac)2–2PPh3–4Et3Al system with the participation of fullerene and diazo compounds.

Hybrid molecules based on fullerene С60 and strained polycyclic hydrocarbons were synthesized for the first time using the Bingel–Hirsch reaction. The films of fullerene derivatives were deposited by centrifugation. The synthesized hybrid fullerene С60derivatives containing one strained polycyclic hydrocarbon moiety showed better charge carrier mobility than the fullerene derivatives containing two polycyclic hydrocarbon moieties. Apart from current–voltage characteristics, the morphology of the prepared hybrid compounds was studied. The best current– voltage characteristics were found for films with lower roughness. The fullerene С60 adducts containing strained polycyclic hydrocarbon moieties were used to fabricate organic field effect transistors (OFETs) with high-quality films; owing to this, the manufacturing process is compatible with modern printed organic electronics.

Through the reaction of fullerenylazide with terminal acetylenes, previously undescribed 1-butyl-2-triazolylfullerenes, in which the heterocyclic fragment was directly attached to the fullerene backbone, were synthesized for the first time. Water-soluble complexes of the synthesized adducts of fullerene with polyvinylpyrrolidone showed a high cytotoxic activity towards tumor cells of the Jurkat, K562, and U937 lines.

Background: With light oil reserves depleting and the demand for lubricants steadily increasing, the development of alternative sources of hydrocarbon feedstock has become a pressing issue. Despite the technological complexity of processing, natural bitumens represent a promising raw material for the production of base oils, particularly in the Republic of Kazakhstan, where domestic industrial lubricant production is currently absent. Aim: To assess the possibility of obtaining base industrial and motor oils from oil fractions derived from the fuel oil of natural bitumen at the Karasaz-Taspas deposit. Materials and methods: on the study object was fuel oil obtained by atmospheric distillation of natural bitumen. Oil fractions with boiling temperature ranges of 350–400 °C and 400–460 °C were separated using vacuum distillation. Purification was carried out using bleaching clay. The physical and chemical characteristics of the fractions were determined before and after purification according to standard ASTM and GOST methods. Results: The obtained oil fractions are characterized by a high kinematic viscosity, a viscosity index of up to 110.7, and low sulfur content (0.45 wt.%). Their physical and chemical properties meet the requirements for base oils of groups I and II according to the American Petroleum Institute classification and are comparable to industrial oils of grades I-40A and I-50A. Dewaxing and the addition of additives are necessary to improve low-temperature performance. Conclusion: Natural bitumen from the Karasyaz-Taspas deposit is a promising raw material for producing high-quality base oils. The study confirms the feasibility of comprehensive processing of natural bitumen fuel oil to produce industrial and motor oils, contributing to the replenishment of the raw material base, the sustainable development of the oil industry, and the enhancement of the country’s energy security.
